Slope
Read full descriptionHide full description
Your gym changes. Your history shouldn't. Slope is a strength-training log that keeps your sets, machine setup notes, PRs, and progress connected to where you train. When the same lift uses different equipment at another gym, Slope keeps the right context with the right location. REMEMBER THE RIGHT SETUP Pin the setup that matters to a lift and gymβseat height, pin, grip, foot position, or anything else you want ready next time. Open it from the workout card or review your notes by gym on the exercise page. SEE LAST TIME HERE Before your next set, see the weight, reps, and notes from your previous session at this location. Repeat a recent workout or start a new one without rebuilding the context. KNOW YOUR SLOPE Slope Score turns your completed strength sessions into a 0β100 view of your training trajectory. See the score on Home, explore its breakdown and trend on Progress, and, when enough history exists, see where the direction turned. KEEP EACH GYM IN CONTEXT History, PRs, weights, and machine notes stay organized by gym. If two differently named lifts are the same movement, you can connect their trend while keeping each location's numbers and notes separate. TRACK WHAT MATTERS Log reps and weight, recognize PRs, follow training volume, monitor goals, review consistency, and spot plateaus. ASK FROM YOUR HISTORY Use Slope AI to ask focused strength-training questions grounded in workouts you've logged. Your core logging, history, and progress tools work without it. Slope is built for lifters who want a fast workout log and a clearer view of what to do nextβwithout a spreadsheet. Slope is a tracking and planning tool, not medical advice. Consult a qualified professional before beginning or changing an exercise program.
